Tag Archives: Rollback

Executing a database manipulation command such as insert, update or delete can sometime throws exception due to invalid data. To protect the integrity of our application data we must make sure when we a transaction was failed we must rollback all the executed command so that it affect the state of our data.

In this example we are using MySQL database. To enable transaction capability in MySQL make sure that you are using InnoDB storage engine to create the your tables.
